She didn't acknowledge him at first. In fact, she kept reading her book as if entirely unaware of his presence, but the stone floors of the cave and the spacious acoustics carried sound to a certain extent, despite any dampening measures Bruce may have taken. She could hear him coming. She knew by the lightness of his footsteps who it was-- someone who did not spend much time with their feet on the ground. The rest would have had their own ways of approaching her. The newest, before Damian, would likely stand back and watch, studiously, waiting to see what she would do before making any moves. Damian, of course, would command the room, even if nothing needed to be said. Jason-- well, she couldn't be entirely sure what Jason's reaction might have been, but she was certain it would begin and end with anger.
Nightwing, however, was different.
Licking her fingers, Talia swept to the next page, still not looking at him or acknowledging his presence. He wanted to see what she was doing, whether she was actually injured or simply faking to gain access to the Cave for some nefarious purpose. Of course, if she wanted to so something terrible to Batman's sanctuary, she would have simply done it and not advertised her involvement, but this boy never thought that far ahead. Emotions clouded his better judgment. They were easy to read on his face.
Still, she gave him his fill, unmoving and unflinching. The harem-style pants Alfred had provided her were worn low, slung just over her hip bones, and the blouse, intended to button up the front so she wouldn't have to keep pulling clothing over her head with her side injury, had only two buttons done, the rest were left open. On her bare side was a fresh bandage, tainted from its pristine white color to something a little yellow, a little orange, a little red. The gash on her back was not visible, but it was also not as severe as the wound in her side.
Now that she was sure he wouldn't make an effort to try to sneak up behind her and push her off the catwalk, Talia spoke up, without turning her startling eyes from the pages of her book.
"If there is something you would like to ask me, please do. Otherwise, I am certain Alfred has taught you that it is rather rude to stare."
